eBay SharePoint 2010 – How We Did It

So the other architect of the eBay SharePoint 2010 Upgrade has started writing up details on how we did the upgrade. At a high level we had to upgrade from a *highly* customized and largely unmanaged organic SharePoint 2007 implementation in to a highly managed SharePoint 2010 instance. We had about 3 1/2 months to bring everything live and upgrade, regression test, create entirely new branding from scratch, move everything en masse between web applications, and largely rewrite the pre-existing custom solutions (over 25 of them). As I find time I’ll also be adding in my own perspective on bits and pieces of the upgrade.
